Heat Pump Repair & Installation Across Flagler & Volusia County, FL
Heat Pump Replacement Company for Northeast Florida
Heat pumps do almost all the heavy lifting in Florida homes, cooling in the summer and heating on the rare cold night, which means when one acts up, it affects your comfort year-round. Whether yours is stuck in defrost mode, blowing cold air in winter, or building up ice, SIMS repairs and installs heat pumps for homes and light commercial properties across Flagler and Volusia County.
LET’S GET YOUR COMFORT BACK
Why Heat Pumps Matter in Florida
Near-year-round cooling and only occasional heating make a heat pump the right tool for our climate, which is why we treat it as its own service rather than folding it into either AC or furnace work. We inspect the system, explain what’s actually wrong, and tell you honestly whether a repair or a new unit makes more sense.
We serve Palm Coast, Daytona Beach, DeLand, Deltona, Ormond Beach, and the surrounding areas of Flagler and Volusia County for both heat pump repair and full installation.
A heat pump asks more of its internal components than a straight AC unit does, since it’s reversing direction and running year-round instead of just in summer. That’s exactly why we treat it as a distinct specialty rather than an add-on to general AC or furnace work.

Signs Your Heat Pump Needs Service
Heat Pump Not Cooling
Could be low refrigerant, a failing compressor, or a reversing valve stuck in the wrong position. We test each component instead of assuming the most expensive cause.
Stuck in Defrost Mode
A heat pump that won’t come out of defrost is often dealing with a sensor or control board issue, and it’s usually a fixable one rather than a sign that the whole unit is failing.
Ice Buildup on the Unit
Some frost in winter is normal. Heavy ice buildup that doesn’t clear on its own usually points to a defrost cycle problem that’s worth checking before it gets worse.
Blowing Cold Air in Winter
This can mean the system has switched to emergency heat, or there’s a genuine heating-mode failure. Either way, it’s worth a diagnostic rather than waiting it out.
Higher Bills Than Usual
A heat pump losing efficiency will often show up on the power bill before it fully fails, which makes an early call worth the cost of the visit.
Short Cycling
Turning on and off too frequently strains the compressor and often means the system is having trouble reaching the set temperature, sometimes due to a refrigerant or sizing issue.

Benefits of Professional Heat Pump Service
Comfort Year-Round
A properly running heat pump handles both sides of Florida weather without you thinking about it, switching between cooling and heating as the seasons actually require.
Lower Operating Costs
ENERGY STAR-certified heat pumps installed correctly can save up to 20 percent on heating and cooling costs compared to an aging unit, which adds up quickly given how hard these systems work here.
Manufacturer Warranty Filing
We handle the registration paperwork on eligible installations, which can extend your coverage well past the standard term instead of leaving you with a shorter one by default.
The Right Brand for Your Home
As a Trane, Daikin, and Mitsubishi dealer, we recommend the unit that fits your home, not whatever is easiest for us to install or has the best margin.
A Guarantee That Backs It Up
Every heat pump repair and installation carries our one-year labor guarantee and 100% satisfaction guarantee, so the promise holds after we leave, not just while we’re there.
What Heat Pump Service Includes
A heat pump repair call includes a full diagnostic of the compressor, refrigerant charge, reversing valve, and defrost controls, with a clear explanation before any work begins.
Installations include correct sizing for your home, manufacturer warranty registration, and a walkthrough of what your new system’s coverage actually includes, so there are no surprises if you ever need to use it. Financing may be available for qualified customers on a full replacement.

Hear It From Your Neighbors
Highly recommend! Spencer quickly came out and diagnosed my problem and even went the extra step to look into warranty after the company that put the unit in would not look into anything for me. Very knowledgeable and fairly priced. I’ll contact them from here on out for all my AC needs!
- Ashton Cassidy
SIMS Heating and air installed a new unit for me last year. My A/C unit had quit and the well known carrier that i had bought the Carrier unit from wouldn’t even return my call, after being a customer for over 12 years. SIMS came through with excellent service and a great new unit.
- Robertson
My elderly mother’s 20 plus year old A/C unit decided to stop cooling. After calling some of the other A/C business, she was told there would be over a week wait. She gave SIMS a call and they had someone out that evening squeezing her in. Fantastic service and great people!
- HL Smith
If moving into a new home is not stressful enough, a finicky A/C unit added to the anxiety. Fortunately, Sims came to the rescue. Instead of the giving me the usual grunts and groans and quotes for a new unit, I got quick, efficient service that solved the problem right away.

Great experience. Fast reliable service. A/C system went down and the next day they were here to replace my system. Great pricing too. I have used them for A/C maintenance as well. Knowledgeable and friendly staff and on time. Lucky to find them.

Heat Pump Questions
Is a heat pump worth it in Florida?
For most homes here, yes. Our near-year-round cooling season and mild winters play to a heat pump’s strengths in a way that colder climates don’t get to enjoy.
How much does a heat pump cost installed?
It depends on the size of your home and the unit you choose. We’ll give you a written price before you commit to anything, with the reasoning behind it explained clearly.
What's the difference between a heat pump and an AC unit?
An AC unit only cools. A heat pump cools in summer and reverses to heat in winter, which is why most homes here use one instead of a separate furnace.
How often should a heat pump be serviced?
We recommend a seasonal tune-up. Ask about our $89 maintenance plan for ongoing coverage and priority scheduling.
Do you install heat pumps for light commercial properties?
Yes, we handle heat pump repair and installation for light commercial buildings as well as homes, sized correctly for the space either way.
